Organic superconductors in particular have been a key system of interest, emerging as the leading candidate for observation of spatially modulated superconductivity owing to their crystals growing relatively cleanly and thus granting the superconducting pairs a long mean free path compared to their coherence length [1]}, their high degree of customizability through the attaching of various functional groups in addition to doping, and their inherently quasi-2D structure, as low dimensionality is expected to enhance FFLO physics [2]}. However, recent experimental developments in the field of ultracold atomic gases [3]} promise new routes to realization of and deep insight into the spatially non-uniform pairing state, with the technique already being used to probe Fermi gases with and without a strong spin-imbalance [4]}, [5]}. The precise level of control and ability to impose spin-imbalance without an applied magnetic field that may disrupt superconductivity make ultracold atomic gases a particularly atractive system.
